High Tolerance: +/- 0.005 mm (0.0002")

X-medics standard bead tolerance is +/- 0.005 mm (AFMBA grade 50) that has been optimized for automated processing and general tolerance requirements when inserted into PEEK and other medical grade materials. For some ball diameters we also offer a lower (+/- 0.02 mm) tolerance that can offered at a slightly lower cost than our standard tolerance.

X-medics’ tantalum balls and beads are available as either standard polished or super polished. The standard polished baeds undergo a single polishing step during ball processing and is is a cost optimized option that is suitable for most applications. The super polished balls undergo several polishing steps and has been developed as a high-end option to be used in critical automated processes.

ASTM F86 Cleaning and Passivation is a standard cleaning procedure to remove particles and process residues from the surface of the tantalum spheres. As ASTM F86 is a cost efficient cleaning method it is specified by 90{1feb32f37b57049aa0371d069a4666091ee93c603ed37b7f2d4d8905fcafb62a} of X-medics’ customers. In some cases ASTM F86 treatment is not suitable, as the the passivation may increase the thickness of natural occurring tantalum oxide layer on the tantalum surface. The thicker tantalum oxide layer may tend to build up static electricity and increase the surface roughness (friction) of the balls.

3rd Party Material test Report Included

Every material lot used in X-medics’ production of tantalum products has been tested by an independent ISO 17025 accredited laboratory to confirm that the tantalum material satisfies the requirements of ASTM F560 / ISO 13782 and is suitable for ball processing. A copy of the independent certificate is provided with all shipments from X-medics. The laboratory analyses the chemical and mechanical characteristics of the wire and compare them again the ISO/ASTM tantalum grade standards.

All X-medics’ tantalum products are conflict-free. X-medics only works with suppliers that can show evidence for a continuously 3rd party auditing performed by independent auditors appointed by Electronic Industry Citizenship Coalition or similar recognized bodies. Proper origin of the materials and compliance Dodd-Frank Wall Street Reform and Consumer Protection Act conflict minerals is required documented and this documentation can be tracked on the certificate that follows any shipment from X-medics. X-medics does not use tantalum minerals with origin in the DRC Congo or other conflict areas covered by the law.
